Development of the traditional Rankine cycle

Does the questioner want to ask what stages the development of the traditional Rankine cycle has gone through.

In the early 19th century, the Rankine cycle was widely used in steam engine power plants.

This Rankine cycle mainly uses coal or oil-fired boilers to heat water into steam, which is then used to generate electricity through a steam turbine.

1. In the early 20th century, as fuel demand increased, people began to study how to improve the efficiency of power plants.

The supercritical Rankine cycle is a more efficient way to generate electricity than the traditional Rankine cycle.

2. In the early 21st century, with the increasing awareness of environmental protection, people began to study how to use waste heat to improve the efficiency of power plants.
